Homemade DIY Billet Aluminum Two-Stroke Engine
Camden Bowen has spent years chasing the perfect two-stroke engine built entirely from scratch. His earlier versions came from a 3D printer and then from parts picked up at the hardware store. Each one taught him something new about what works and what falls short under real fire. For his latest project he set a higher bar and machined the whole thing from billet aluminum on a basic mill and lathe.

Bugatti Tourbillon Specs Cold Weather Testing Sweden
Engineers and drivers gathered at the Colmis Proving Ground in Arjeplog, northern Sweden, for a four-week endurance test of the new Bugatti Tourbillon hypercar under the worst winter conditions possible. As they arrived, the place was a winter paradise (or nightmare), with snow piled up everywhere and temps starting at -30 degrees. Conditions were also slippery, with drivers encountering a mix of slick ice, hard-packed snow, slush, and even some asphalt, which presented some unexpected surprises. Their mission was simple: ensure that every function in the automobile worked flawlessly regardless of the weather.

Razer Kishi V3 iPhone Android Game Controller
When mobile gamers rely solely on touchscreens, they face numerous challenges. Swipes miss their target at the worst possible times, fingers slip during frantic sequences, and sophisticated games require more dexterity than a flat glass surface can provide. The Razer Kishi V3, priced at $74.99 after clipping the on-page coupon (was $100), is a basic solution that clamps onto your phone and provides tactile controls designed for serious play.

James Webb Space Telescope Messier 77 M77 Galaxy

Astronomers released an image this week that pulls viewers straight into the dynamic core of Messier 77 (M77). Located 45 million light-years away in the constellation Cetus, this barred spiral galaxy offers a clear target for study thanks to its relative closeness and the range of activity packed inside its structure. Captured entirely in mid-infrared light by the James Webb Space Telescope’s specialized instrument, the view highlights details that ordinary light cannot reach.

GENE-26.5 AI Brain Robots Human Capability
Genesis AI just released a new AI model called GENE-26.5 that lets robots handle everyday objects with the same ease and precision people use. In tech demos released this week, one robot cracks an egg with one hand without spilling a drop, then uses both hands to chop tomatoes and stir a pan during a full meal. Another sorts four different items into bins using just its fingers, while a third solves a Rubik’s Cube in mid-air with quick wrist turns and steady grips.

3D-Printed Electric Turbofan Model
CADLY poured months of design effort into creating an electric turbofan model that anyone can produce at home. Files sit ready for download from the maker’s own site or the Printables page, and a standard 3D printer handles every major piece. The finished unit draws direct inspiration from the CFM56 engines found on Airbus A320 airliners, yet it runs on basic electronics and a small motor instead of jet fuel.
